How does the sensitivity and specificity of the ELISA test compare to that of the Western blot method?

Show Answers

Lower sensitivity and lower specificityHigher sensitivity and higher specificityLower sensitivity but higher specificityHigher sensitivity but lower specificityNone of the above

Explanation

When comparing ELISA to Western blot, ELISA generally exhibits greater sensitivity but reduced specificity. This means ELISA is better at detecting the presence of antibodies or antigens, but it is more prone to false positives compared to the more specific Western blot technique.
